Are Patients at Veterans Affairs Medical Centers Sicker?
BACKGROUND: The Veterans Affairs (VA) health system has been criticized for being inefficient based on comparisons of VA care with non-VA care. Whether such comparisons are biased by differences between the VA patient population and the non-VA patient population is not known. Our objective is to determine if VA patients are different from non-VA patients in terms of health status and medical resource use. METHOD: We analyzed 128,099 records from …
Outpatient Internal Medicine Preoperative Evaluation
The purpose of this study was to evaluate the effect on resource use of a program outpatient internal medicine preoperative evaluation in a two arm parallel design randomized clinical trial. In a tertiary care teaching Veterans Affairs hospital, 355 patients (179 inpatient arm, 176 outpatient arm)(mean age 65.5 years) were referred for internal medicine preoperative evaluation before elective surgery. Outpatient internist preoperative evaluation …
Racial Differences in the Use of Invasive Cardiovascular Procedures in the Department of Veterans Affairs Medical System
BACKGROUND: Previous studies have found racial differences in the use of invasive cardiovascular procedures, which may be due in part to the greater financial incentives to perform such procedures in white patients. In Department of Veterans Affairs hospitals, direct financial incentives affecting use of the procedures are minimized for both patients and physicians. METHODS: We conducted a retrospective analysis of the use of cardiovascular proce…
The effect of fish oil supplements on blood pressure
We conducted a double-blind, placebo-controlled crossover study to determine the effects of fish oil supplementation on blood pressure in middle-aged men. Subjects were randomly assigned to consume either 20 g of fish oil or safflower oil for 12 weeks and then consume the other oil for an additional 12 weeks after a 4-week washout period. We found no significant changes from the pretreatment value in systolic or diastolic blood pressure with the …
Teaching status and resource use for patients with acute myocardial infarction
To investigate whether the process of graduate medical education increases costs in teaching hospitals by causing longer lengths of stay and greater resource use, we compared lengths of stay, hospital charges, and the use of cardiovascular procedures for patients with acute myocardial infarction admitted to the teaching and nonteaching services of a university-affiliated community hospital. After adjusting for severity of illness and demographic …
Mechanical restraints on the medical wards
We prospectively identified 102 mechanically restrained hospital patients and determined their hospital course. The cohort was elderly, cognitively impaired with multiple chronic diseases. The in-hospital mortality was 21 percent. Nosocomial infection developed in 12 percent and new pressure sores in 22 percent. Prolonged use of restraints (greater than 4 days) was the strongest independent predictor of nosocomial infection (relative risk 1.8, 95…
A profile of the self-poisoner in Michigan
We reviewed the charts of all patients (160) ages 15 and older discharged in 1981 from the four hospitals in Lansing, Michigan with a diagnosis of overdose. Females predominated (65 per cent) and the median age was 27 years. The most common reason for intentional self-poisoning was "significant-other" conflict (54.5 per cent), followed by family conflict and financial problems. Benzodiazepines were most commonly used followed by acetylsalicylic a…
